A day after spending an afternoon at an amazing Dog Park in WInter Park FL, my dogs refused to eat and now are even vomiting water, one is a mixed breed terrier and one is a pappillon. The only thing, there is a lake on property and both dogs drank out of the lake. There must have been over 200 dogs there. Many in and out of the water. The weekend is here and no vet to take them to. Wasn't sure if we should try tagamet or reglan or wait and let things cool off. Don't want them to get dehydrated. ANy foods to recommend as they cannot tolerated there food or now water. Could a parasite work that quickly? Not sure what is going on. Please help before they get sick. Thanks

I hope you can get to them to the vet as soon as the vet is open.

In the meantime, when my dogs would get upset stomachs, the vet told us to boil some rice (minute rice) and boil chicken breast.

Mix the two of them together and hopefully they will eat for you.

Let us know how you do and hoping for the best.
